Tobolsk Oil Pipeline Directorate affiliated with Transneft Siberia is about to finish replacing a standby leg of the Surgut – Gorky – Polotsk oil trunk pipeline (OTP) at the section from 348.83 to 358 km (Tyumen Region). The OTP is being technically upgraded in line with the Company’s development programme.

The work started in December 2017. All standby leg works have been completed by now and a new section has been connected to the working oil pipeline.

The total length of the replaced standby leg section is 9,622 metres. The work included the replacement of the oil pipeline’s underwater crossings at the rivers Kirgaz and Bolshaya Kondinka. In the stream bed of water obstacles, the pipeline was laid by pulling a siphon along the bottom of an underwater trench. The facility is expected to be commissioned in May 2018, after technical rehabilitation is completed.

The technical upgrading of the standby leg section at the Surgut – Gorky – Polotsk OTP is being carried out to ensure the emergency-free operation and the environmental safety of Transneft Siberia’s oil trunk pipeline system.
